Ukusika akuyonto inzima: Sebenzisa iiblade zesarha ze-carbide ukuze ufumane ukucubungula okukrelekrele
Xa kusahwa izinto ezinzima ukucutshungulwa (ezifana nee-alloys ze-titanium, intsimbi engatyiwayo, ii-alloys ezimelana nobushushu kunye neentsimbi eziqinileyo), ii-carbide tooth band saw blades ziye zaba zizixhobo ezisetyenziswa kakhulu ngenxa yokuba zintle kakhulu.ukusikaukusebenza kakuhle nokuqina. Kwiminyaka yakutshanje, abasebenzisi abaninzi baye baqalisa ukuzisebenzisa ekucutshungulweni kwezinto eziqhelekileyo kwaye bafumanise ukuba zinesantya sokusika esikhawulezayo, ukugqitywa kakuhle komphezulu, kwaye zinokunyusa ubomi benkonzo malunga ne-20% xa kuthelekiswa neebhlawu zesarha ze-bimetallic zemveli.
1. Ulwakhiwo lwamazinyo kunye nejometri
Iimilo zamazinyo eziqhelekileyo zeeblade zesarha ze-carbide ziquka ukusika amazinyo amathathu kunye namazinyo okusila e-trapezoidal. Phakathi kwazo, imilo yamazinyo okusila amazinyo amathathu idla ngokusebenzisa uyilo lwe-angle yeraki elungileyo, enceda "ukuluma" ngokukhawuleza izinto kunye nokwenza iitships kwizixhobo ezinamandla okanye ezinzima, kwaye zifanelekile kwiimeko zemveliso ezisebenzayo. Xa kusetyenzwa izinto eziqinileyo kumphezulu (ezifana neentonga zesilinda okanye iishafts ze-hydraulic), kucetyiswa ngakumbi ukusebenzisa imilo yamazinyo e-angle yeraki engalunganga. Olu lwakhiwo lunceda "ukutyhala" umaleko womphezulu oqinileyo phantsi kweemeko zobushushu obuphezulu, ngaloo ndlela kugqitywe ukusika kakuhle.
Kwizinto ezirhabaxa ezifana ne-casti-aluminiyamu, iiblade zesarha zebhendi ezinepitch yamazinyo ebanzi kunye noyilo lwegroove yokusika ebanzi zifanelekile ngakumbi, nto leyo enokunciphisa ngempumelelo amandla okubamba kwezinto ezingasemva kweblade yesarha kwaye yandise ubomi besixhobo.
2. Iindidi ezahlukeneyo zeeblade zesarha kunye nobubanzi bazo obufanelekileyo
· Izinto ezincinci ezinobubanzi (<152mm): Zifanelekile kwiiblade zesarha zekhabhayidi ezinesakhiwo samazinyo amathathu kunye nomfanekiso wezinyo we-rake positive angle, kunye nokusebenza kakuhle kokusika kunye nokuguquguquka kwezinto.
· Izinto ezinkulu ezinobubanzi: Kucetyiswa ukusebenzisa iiblade zesarha ezinoyilo olunemiphetho emininzi, ngokuqhelekileyo zigaya ukuya kuthi ga kwiindawo ezintlanu zokugawula kwincam nganye yezinyo ukuphucula amandla okugawula nokuphucula izinga lokususa izinto.
· Izixhobo zokuqinisa umphezulu: Kufuneka kukhethwe i-negative rake angle kunye neebhlawu zesarha ezinamazinyo amathathu, ezinokusika ngobushushu obuphezulu kunye nokususa iitshiphusi ngokukhawuleza, kwaye zisike ngempumelelo iqokobhe eliqinileyo langaphandle.
· Iintsimbi ezingezizo iintsimbi kunye ne-aluminium ephosiweyo: Zifanelekile kwiibhleyidi zesarha ezinoyilo olubanzi lokutyibilika kwamazinyo ukuze kuthintelwe ukubanjwa kwe-grooving kunye nokunciphisa ukungasebenzi kakuhle kwangethuba.
· Iimeko zokusika ngokubanzi: Kucetyiswa ukusebenzisa iiblade zesarha zebhanti ye-carbide eziqhelekileyo ezinesimo samazinyo esingathathi cala okanye esincinci esifanelekileyo, ezifanelekileyo kwiintlobo ngeentlobo zeemilo zezinto kunye neemfuno zokusika.
3. Impembelelo yohlobo lwamazinyo kumgangatho wokusika
Iintlobo ezahlukeneyo zamazinyo zihambelana neendlela ezahlukeneyo zokwenza iitships. Umzekelo, uyilo olunye lusebenzisa amazinyo amane asemhlabeni ukwenza iitships ezisixhenxe. Ngexesha lenkqubo yokusika, izinyo ngalinye labelana ngokulinganayo ngomthwalo, nto leyo enceda ekufumaneni umphezulu wokusika othambileyo nothe tye. Olunye uyilo lusebenzisa isakhiwo samazinyo amathathu ukusika iitships ezintlanu. Nangona uburhabaxa bomphezulu buphezulu kancinci, isantya sokusika sikhawuleza, nto leyo efanelekileyo kwiimeko zokucubungula apho ukusebenza kakuhle kubekwa phambili.
4. Ukwaleka kunye nokupholisa
Ezinye iiblayidi zesarha ye-carbide zibonelela ngezinto ezongezelelweyo zokugquma, ezifana ne-titanium nitride (TiN) kunye ne-aluminium titanium nitride (AlTiN), ukuphucula ukumelana nokuguguleka kunye nokumelana nobushushu, kwaye zifanelekile kwizicelo ezikhawulezayo nezondla kakhulu. Kubalulekile ukuqaphela ukuba iintlobo ezahlukeneyo zokugquma zifanelekile kwiimeko ezahlukeneyo zokusebenza, kwaye ukuba kufuneka kusetyenziswe izinto zokugquma kufuneka kuqwalaselwe ngokupheleleyo ngokusekelwe kwiimeko ezithile zokusetyenziswa.
